发明名称 System and method for compressing textual image data
摘要 <p>A novel system and method for compressing image data scanned by an optical scanner (346) is presented. The scanned image is divided into a predetermined number of cells (510). Each cell is then compressed (540) based upon a classification (530); the classifications are determined via histogram analysis (520) of each cell. The present method allows for decompressing the entire image, as well as any area of the scanned image by way of an identifier byte. &lt;IMAGE&gt;</p>
